System unexpectedly stops working on the main screen.
System unexpectedly stops working on the main screen.
Today my PC unexpectedly shut down and then froze with a BSOD. This is occurring even when I’m sitting on the desktop with only Discord and Wallpaper Engine running. My system is quite old, so it hasn’t always been reliable. Usually I just boot up games without any other programs, but this new issue has happened several times lately.
My specs are: CPU – Amd Athlon x4 760k, Memory – 16 GB DDR3 1333 MHz, Storage – 1 TB HDD, GPU – GTX 1060 6 GB. When I say the PC freezes, it means everything stops responding—keyboard, mouse, even Ctrl+Alt+Del don’t work. The video stays on but freezes too. After a short time, it triggers a bluescreen with the “Synthetic Watchdog Timeout” error.
I’ve looked in Event Viewer for errors and found no WHEA messages, so if there’s a hardware problem it might not be obvious. I also checked critical errors, but they’re mostly consistent with past crashes—just Kernel-Power ID 41 warnings.
How should I tackle this problem?
It might be an aging HDD, especially if it's as old as the other components. Alternatively, the issue could relate to RAM. Consider resetting CMOS and replacing the CMOS battery. CR2032.
Navigate to C:\Windows\Minidump and verify the presence of any minidump files. If found, return to the Windows directory and transfer the Minidump folder to the Downloads folder (use your desktop if needed). Compress the copied folder and include it in a post. Avoid messing around in C:\Windows and stick to the instructions carefully.
Major change noticed—my CPU seems to be idling around 80 degrees. The case inspection revealed the exhaust fan isn’t turning. It looks like the thermal paste hasn’t been replaced recently, so I plan to go to MicroCenter to swap it out and check the situation.
Purchase an SSD as well. The system would operate significantly more smoothly, with much faster loading times.
Monitor the temperatures closely. Any CPU problems are likely the primary concern.
The problem seems fixed! I received a replacement fan and thermal paste. After taking out the cooler, I found the thermal paste was fully dried up with almost no residue left. I’m not sure how it operated before this. My PC was purchased from an auction site a few months ago, and I believe the previous owner never changed the thermal paste during those 12 years. Now, it’s running smoothly while downloading my Steam library at around 50%. I also installed an SSD and switched to Linux, which has significantly improved performance.
